Last night, UKTV show “Tonight” broadcast a 30 minute documentary called “Facing up to Facebook”.

As well as looking into some of the great things that Facebook can do (for instance, they told the story of how the family of a British man who had been critically injured while holidaying in Mexico had managed to find blood donors via the site), it also examined some of the problems with the site.
